What about option 6?

Create a GPG key and encrypt / decrypt your messages.

It takes about 10 minutes once to set up your key and then it's easy to send and receive encrypted messages with no central server since you could send the encrypted text over whatever transport mechanism you prefer (gist, email, etc.).

We kinda did this with the snip cli (which is one of our other repos besides the ots cli). It's basically a wrapper around PGP with some additional features like vaults to facilitate sharing PGP encrypted secrets with a team. And... It takes less than 10 minutes to set up :P
